On a separate sheet of
paper, make sketches of the home showing all sides. Measure
the height of each side at the corner and multiply that
by the width to attain the surface area of that side.
Step
2
Measure gables, dormers
and any other area not included by the sides. For each
triangular-shaped area measure from the base to the top,
then multiply by 1/2 the base length. Then add all areas
together.
Step
3
Measure the windows, doors,
or any other area that will not be covered with siding.
Multiply width x height for each area, then add all areas
together.
Step
4
Take the total area from
Steps 1 and 2 and add them together. Then, subtract total
of Step 3 from the total of Steps 1 and 2. Always add
10% for waste and/or miscalculation of material.
Step
5
To determine the amount
of siding squared needed, remember that 100 square feet
of surface area equals one square, so divide your footage
from Step 4 by 100.
